Kassia Krozser has a Cluetrain-like manifesto for publishers. From Booksquare:
It’s time to get your hands dirty, to dig into the real-world conversation. It’s a weird thing, and sometimes awkward and uncomfortable, especially if you’re accustomed to public relations-speak and the cheerleader behavior that accompanies marketing messages. When you talk directly to real people who read and buy books, they tune you out when you try to stay on message. If they wanted to rehash cover copy, they’d read the back of the book.
